Methods and apparatus for implementing an access point supporting multiple communications protocols

ABSTRACT

Access points can be mounted in a variety of locations or orientations and can support multiple communications protocols. In some embodiments, an access point includes a main housing and a front housing. The main and front housing are connected by a hinge. A Wi-Fi antenna is included in the front housing in some embodiments. The access point is configured for use in either an open or closed position. When mounted in a vertical position, the front housing can be lowered into a horizontal position, which facilitates a preferred orientation of an antenna with respect to the ground. A first set of cooling fins serves to maintain components of the access point offset from a wall to which the access point is mounted. This facilitates airflow. Additional fins act as a spacer between the main housing and the front housing when the access point is used in a closed position. This facilitates air flow around both sides of the main housing.

FIELD

The present application is directed to access point methods and apparatus and, more particularly, to access points which can be mounted in a variety of locations and orientations and which can support multiple communications protocols, e.g., Bluetooth and/or Wi-Fi.

BACKGROUND

Access points which often have flat backs to allow for mounting to a wall. Such devices can be subject to overheating issues with limited opportunity for air cooling due to the flat mounting to the wall.

While some antennas can work well while mounted vertically, in the case of a Bluetooth Low Energy (BLE) antenna array intended to transmit to devices below the access point a horizontal orientation of the array can be desirable from a radio transmission coverage area perspective.

While it would be desirable to allow for vertical mounting of an access point to a wall or pole, it would also be desirable if it were possible to have a BLE antenna array in the horizontal position for access points which are likely to be mounted above devices which are likely to communicate to the access point.

In view of the above there is a need for new access points which address one or more of the cooling and/or antenna array positioning issues discussed above.

SUMMARY

An Access Point in some embodiments includes a housing, e.g., a waterproof main housing with cooling fins and a front housing which includes one or more antennas. A hinge allows movement of the front housing so that it can be positioned in a vertical position against the main housing in a horizontal position, e.g., parallel to the ground at 90 degrees to the vertically oriented main housing.

Indoor embodiments can use the same or similar housing but it need not be waterproof in the case of indoor applications. A Wi-Fi antenna may be and sometimes are attached through connectors on the main housing. The main housing and/or WiFi antenna can be mounted to a pole or wall. Alternatively an internal Wi-Fi antenna included in the front portion of the housing in at least some but not necessarily all embodiments can be, and sometimes is, used to support Bluetooth and/or Wi-Fi. In some embodiments a Bluetooth antenna assembly, e.g.., a BLE array, is included in a moveable front housing with one or more LED status indicators being mounted in the front housing and visible from the outside of the front housing. The LED status indicator(s) can and sometimes do indicate that the access point is active, e.g., powered on. Flashing of the indicator can be used to communicate various status conditions. While one LED indicator is included in various exemplary embodiments, additional indicator lights may be and sometimes are included and used to communicate particular status information such as Wi-Fi status active, Bluetooth status active, in addition to general power on which may be and sometimes is indicated by a third LED. The front housing assembly is secured to the main housing by a hinge. The hinge in some embodiments is located at the bottom of the main and front housings. Power and data connections are provided via a secure waterproof cable connection, e.g., passing through a watertight tube between the main and front housings, to allow the components in the main and front housings to interact. The access point can be wall or pole mounted.

The main front housing, which includes the Bluetooth antenna assembly, includes one or more antenna elements used to transmit and/or receive Bluetooth signals, e.g., BLE signals, and can be used in a vertical or horizontal position. The position of the front housing is detected and reported to a processor in the access point and, optionally, one or more devices coupled to the access point by an interface and/or Wi-Fi signals. The position is detected by a sensor or sensor array located in the front housing. The sensors may and sometimes do include one or more accelerometers. The detected position of the Bluetooth and/or included Wi-Fi antenna is known from the reported housing position information, e.g., relative to the ground, with the positions being detected by sensors in the access point and communicated to one or more devices which use the access point or process measurements of signals received from the access point. Thus the position information which allows for the Bluetooth and/or Wi-Fi antenna position, e.g., vertical, horizontal or at some angle relative to horizontal, being useful in facilitating position determinations made from signals received from the access point since the RF coverage/path loss for signals transmitted by the access point can be estimated by taking into consideration the position of the antenna(s) relative to the ground. The position of cooling fins between the front and main housing portions allows air to pass through the device and cool both the main and front assemblies.

Water tight connectors allow for the supply of power and antenna connections. Cooling fins on the back of the main housing which may be secured against a wall allow for air to pass between the wall and main access point housing even when secured directly to a wall. Thus air can flow around each side of the main and front housing in both wall and poll deployments since the arrangement of cooling fins allow for air flow between and behind the front and main housings and behind the main body housing. Air can also pass along the front of the front body since it is normally exposed in either the open or closed positions access point modes of operation. A pressure vent is included to allow venting in the case of pressure build up, e.g., due to heating, without letting water in. The Bluetooth antenna can be used in the vertical or horizontal front assembly positions with knowledge of the position being known from the position sensor(s) allowing the orientation of the Bluetooth front assembly and antenna to be taken into consideration when making coverage and/or Bluetooth coverage area predictions which can be used, e.g., to facilitate location determination. Access Point -supporting Wifi, e.g., In some embodiments the access points supports 802.11 and Bluetooth, e.g., Bluetooth Low Energy (BLE) communications protocols and wireless signals.

Numerous features and embodiments are described in the detailed description which follows.

DETAILED DESCRIPTION

Various embodiments are directed to an access point which can receive and transmit wireless signals, e.g., Bluetooth and/or Wi-Fi signals. The access point in an outdoor embodiment is waterproof. The indoor embodiment need not be and sometimes is not waterproof.

FIG. 1 shows various views, 1001, 1002, 1004, 1006, 1008 and 1010 of an access point 1000. Other figures show the same access point or a similar access point. It should be appreciated that features shown in the different illustrated embodiments shown in different figures can be used together in a single access point. Accordingly, while the exemplary access points shown in different figures may have some different features, the features may be combined and used together. Given the commonality between the various illustrated access points shown in the various figures of the application, reference numbers which are the same in different figures are used to refer to the same or a similar component. Accordingly once an element shown in one figure, and identified by a reference number, is discussed and explained, the element identified using the same reference number in a later figure may not be discussed again with regard to the later figure for the sake of brevity.

FIG. 1 shows an embodiment of an access point 1000 that supports Wi-Fi, e.g., 802.11 and Bluetooth. In some embodiments an access point 1000 includes a main housing 102 including an outer shell and an inner cover 106. The main housing is also sometimes referred to as a main body. The access point also includes a front housing 104 which is connected to the main housing 102 by a hinge 108. The front housing 104 is held at 90 degrees in some embodiments to the main housing 102 by a bracket 117 that controls how far the front housing 104 can swing down from the main housing 102 when in the open position. On some embodiments such as the one shown in FIG. 2 , a waterproof tube 255 is used as a passageway between the main housing 102 which includes main housing shell 105 and the front housing 104.

The components of the access point 1000 and their arrangement can be better understood from the various perspectives 1001, 1002, 1004, 1006, 1008 and 1010 shown in FIG. 1 . In each of the FIG. 1 perspectives the access point 1000 is shown in an open position, e.g., with the front housing 104 being positioned perpendicular to the main housing 102 which includes the main housing outer shell 105. This arrangement, e.g., an open access point arrangement, is commonly used when the access point is pole mounted or mounted to a wall of a building or room. By positioning the front housing 104 in a horizontal orientation, a BLE antenna array and/or WiFi antenna in the front housing 104 are well positioned for transmitting and/or receiving wireless signals from devices positioned below the access point 1000.

View 1001 is a first side view showing the access point 1000 in an open position. View 1002 is a downward looking view showing the top of the main housing and the inside cover 132 of the front housing 104. View 1004 is a front view with inside cover 106 of the main housing being visible. View 1006 is an upward facing view showing what might be seen by looking up when the access point 1000 is mounted to a wall or pole and the access point is in the open position. Note that in this position one or more status indicators 206 which may be and sometimes are implemented as LEDs can be observed from the ground when the access point is mounted at a height which is normally above a person’s head, e.g., 8 feet, 10 feet or more above the ground. Plugs 300, 301 and 302 which can be removed for connecting to conduit or for other reasons, e.g., to allow for the supply of power to the access point, are visible in view 1006. View 1008 is a perspective view of the open access point 1000. View 1010 is a second side view of the access point 1000.

The main housing 102 and front housing 104 are water tight enclosures in outdoor embodiments. In the case of indoor embodiments the access point 1000 can use the same or similar housing to that of the outdoor embodiment but the main and front housing 102, 104 need not be water tight in the case of indoor applications. In the case of an indoor embodiment the flexible watertight tube 255 shown in FIG. 2 for protecting wireless extending from the main housing 102 to the components in the front housing 104 can be omitted.

Depending on the embodiment a Wi-Fi antenna is either included in the front housing 104 or an external Wi-Fi antenna can be coupled to the AP via a waterproof antenna connector located in the top of the main housing 102 in some embodiments. The main housing 102 is formed of an outer shell 105 and an inner cover 106. The inner cover 106 can be inserted into and secured to the outer cover 105 via screws 110. In various embodiments the inner cover 106 of the main housing includes cooling fins 120′ which like the cooling fins 120 of the main housing shell 105 radiate heat and facilitate the circulation of air. Given the presence of cooling fins 120, 120′ air flow over both sides of the main housing 102 in which heat generating components are positioned regardless of the mounting arrangement and whether or not the access point is used in an open or closed position. An optional gasket can be and sometimes is placed between the outer shell 105 and inner cover 106 to make the main housing water tight. The outer cover 105 includes a plurality of cooling fins 120 on the outside surface of the outer cover 105 arranged so that they are in a vertical position when the access point 100 is mounted to a wall or pole as illustrated in FIG. 6 . The inner cover 106 also includes a plurality of cooling fins 120′ which are arranged so that the fins are in a vertical position when the access point is mounted to a wall or pole.

The fins 120 serve as a spacer to keep the internal components of the access point off a wall when they are mounted to a wall and to allow for air flow through the fins for cooling even when the access point 100 is mounted directly to a wall. The fins also serve as a heat radiating element providing more cooling surface area for heat transfer than would be available if a flat surface was used for the outer shell 105 of the main housing 102. The additional fins 120′ on the inside cover 106 of the main body 102 act as a spacer between the surface of the inner cover 106 and the front housing when the access point 100 is used in a closed position. In this way the main housing 102 will have air flow on both sides through the fins 120 and/or 120′ by natural convection when the access point 1000 is mounted whether the front housing 104 is in an up, e.g., closed, position or down, e.g., open position.

The front housing 104 includes outer shell 130 and an inner cover 132 which are secured together by screws 136. A gasket maybe and sometimes is used between the inner cover 132 and the outer shell 130 of the front housing 104 to form a watertight enclosure. An external Wi-Fi antenna maybe and sometimes is attached through a watertight connector 140 included at the top of the main housing 102. A pressure release value 155 is included in some embodiments to allow for automatic venting of the main body 102 in the event of changes in atmospheric pressure or changes in pressure due to changes in height of the access point as it is installed on a poll or another support structure such as the wall of an outside wall of building or room in a building.

An external Wi-Fi antenna maybe and sometimes is attached through a watertight connector 140 included at the top of the main housing 102 which can be mounted to a pole 160 or wall is see, e.g., FIGS. 5 and 6 showing pole mounting. As illustrated in FIG. 4 , alternatively an internal Wi-Fi antenna 202 included in the front housing 104 can be used to support Wi-Fi. A Bluetooth antenna assembly 204, e.g.., a BLE array or matrix, is included in the moveable front housing 104 with one or more LED status indicators 206 being mounted in the front housing 104 and visible from the outside of the front housing 104. The LED status indicator(s) can and sometimes do indicate that the access point is active, e.g., powered on. The flashing of the indicator can be used to communicate various status conditions. While one LED indicator 206 is shown in FIG. 1 and various other figures, additional indicator lights may be and sometimes are included and used to communicate particular status information such as Wi-Fi status active, Bluetooth status active, in addition to general power on which maybe and sometimes is indicated by a third LED. The front housing assembly 104 is secured to the main housing by one or more hinges located 108 , in some embodiments, at the bottom of the main and front housings 102, 104.

Power can be supplied to the access point 1000 by removing one of the plugs 302 and running a power line from an electrical conduit screwed into the threaded opening where the plug 300, 301 or 302 was located and connecting the power line to the components in the main body to supply power there to.

Power and data connections between the components in the main housing 102 and front housing 104 are provided via a secure waterproof cable connection, e.g., passing through a watertight tube 255 between the main and front housings, to allow the components in the main and front housings to interact.

FIG. 2 shows a perspective view 1012 of one exemplary embodiment of the access point 1000 of FIG. 1 with a watertight tube 255 being used to protect wires extending between the main housing 102 and front housing 104. In the FIG. 2 example a faster 107, which can be a snap, screw or other type of fastener, and which can be inserted or snapped into fastener receiver 107′ is visible. The location of fastener 107 and fastener receiver 107′ can vary depending on the embodiment. In the case where the fastener 107 is a screw the fastener receiver 107′ maybe a threaded hole.

FIG. 3 is a set of diagrams showing various perspectives 1014, 1016, 1018, 1020, 1022, 1024, 1026, 1028 of the exemplary access point 1000 shown in FIG. 1 and various other figures in a closed position. The various numbered components shown in FIG. 3 have already been discussed with regard to FIG. 1 and thus will not be discussed again with regard to FIG. 3 .

FIG. 4 , is a block diagram 400 showing he components 402 included in the main housing 104 and the components 404 included in the front housing 102 of the access point 1000 shown in FIG. 1 and the other figures. As previously discussed wires, e.g., of one or more buses, connect the components in the main 102 and front housing 104. The wires 272, 274, 276, 278 and/or 280 can and sometimes do pass through the waterproof tube 255 shown in FIG. 2 . The dashed line 271 represents the connection between components in the main housing 102 and front housing 104, e.g., via the tube 255. In some embodiments the components 402 included in the main body are mounted on a printed circuit board. The components 402 in the main body 102 include a trusted platform module (TPM) 230, master control unit (MCU) 232, memory 234, central processing unit (CPU) 208, Wi-Fi radio or radios 238, a Wi-Fi scan radio 240, a BLE radio 250, console ports and LEDs 236 and Ethernet ports 210. In various embodiments, the CPU, WiFi radios and BLE radio are mounted in a watertight cavity of the main body 102 where the cavity is formed by a void between the outer shell 105 and cover 106. The pressure vent 155 vents the cavity to the outside environment thereby avoiding pressure build up in the cavity and/or pressure equalization between the cavity and an environment in which the access point 1000 is located, e.g., mounted.

The TPM 230 is a chip that stores encryption keys, e.g., RSA encryption keys, specific to the access point for hardware authentication. The CPU 208 and/or MCU 232 control the access point to receive and transmit signals, e.g., WIFI and/or BLE signals and to communicate information, e.g., via an Ethernet port 210 to/from a network device and/or the Internet. The components 402 inside the main housing 102 are coupled to the components 404 in the front housing 104 via cables or ports which extend through the main housing 102 in a manner that allows for a watertight seal in at least some embodiments. The components 404 in the front housing 104 include antennas 202, 204, 406 and/or other components such as tilt sensor 212 and LED or LEDs 206 which provide a status indication. In some embodiments a water tight tube or enclosure 255 as illustrated in FIGS. 2 and 7 , is used to protect cables 272, 274, 276, 278, 280 as they pass from the main body 102 including outer shell 105, to the front housing 104. Tube/enclosure 255 is used to form a water tight flexible passage from the inside of the main housing 102 to the inside of the front housing 104 while the cooling fins 120 on the main body 102 and cooling fins 120′ on the cover 106 allow the components included in the compartment formed by the main body 102 and cover 106 to dissipate heat.

The access point 1000 of FIG. 1 and the other Figures can be wall or pole mounted. FIGS. 5 and 6 include diagrams 500, 600, respectively, showing exemplary access points mounted to a pole 160. The mounted access points can be the same or similar to the access points shown in any of the other figures. Note that in the FIG. 6 example a screw, snap or other fastener 117 is positioned on the side rather than on the top of the access point and can be used to secure the access point front housing 104 in a closed position.

FIG. 7 is a diagram 700 showing an exemplary access point which maybe the same or similar to the access point shown in any of the other figures in a open position with a retaining bracket 117 being shown and the waterproof cover 255 also being shown. In the FIG. 7 example a screw 708 is used to hold the bracket 117 in a position in which the bracket is secured when the access point shown in FIG. 7 is in the closed position. Note that recess 701 prevents the head of the screw 708 interfering with the front housing 104 when the access point is in the closed position. When setting the access point front cover 104 into the horizontal position, screw 708 will be removed and used to secure the bracket 117 to the front cover by screwing the screw 708 into threaded shaft/hole 702. Note that in FIG. 7 the inside cover 706 of the front housing 104 includes standoffs 704 to maintain proper spacing between the inside cover 704 of the front housing and the inside cover 106 of the main body 102 which includes outer shell 105.

Referring now to FIG. 8 , a diagram 800 shows the exemplary access point of FIG. 7 with the bracket 117 deployed to maintain the front housing 104 in a horizontal position. Arrow 801 represents the fact that as part of deploying the front housing 104 into the horizontal position the cover will be hinged outward from the upright closed position to the horizontal position shown in FIG. 8 .

FIG. 11 is a side cut away view of an exemplary access point, such as the access point of any of the other figures, in which the antenna array in the front housing can be seen and various other components in the main housing can be seen.

FIG. 12 is a view of an exemplary access point, such as the access point of any of the other figures, with the front cover being shown as transparent allowing the antenna array and other elements in the front housing to be seen.

The main front housing , as shown in FIG. 11 , includes the Bluetooth antenna assembly, includes one or more antenna elements used to transmit and/or receive Bluetooth signals, e.g., BLE signals, and can be used in a vertical or horizontal position. The position of the front housing 104 is detected and reported to a processor in the access point 208 and, optionally, one or more devices coupled to the access point by an interface e.g., Ethernet Ports 210 and/or Wi-Fi signals. The position is detected by a sensor 212 or sensor array located in the front housing 104. The sensors 212 may and sometimes do include one or more accelerometers. The detected position of the Bluetooth and/or included Wi-Fi antenna is known from the reported housing position information, e.g., relative to the ground, with the positions being detected by sensors in the access point and communicated to one or more devices which use the access point or process measurements of signals received from the access point. The height from the ground and/or GPS determined location maybe determined and reported by sensors 212 in addition to the tilt or angle of the front housing 104. Thus from the angle of the housing 104 the orientation or angle to the ground maybe known while GPS or other sensor information may provide the height and location of the access point 100 in the environment. The front housing tilt information provides Bluetooth and/or Wi-Fi antenna position orientation information, e.g., vertical, horizontal or at some angle relative to horizontal, which is useful in understanding the radiation pattern which will be generated by the access point 100. Such information can be important in facilitating position determinations made from signals received from the access point since the RF coverage and/or path loss for signals transmitted by the access point can be estimated taking into consideration the position of the antenna(s) relative to the ground.

FIG. 9 shows a side view 900 of an exemplary outdoor access point, which is the same or similar to the access point of FIG. 1 or the other figures.

FIG. 10 is upward facing view 1100 of an access point which is the same or similar to the access point of the other figures. The bottom of the access point can be seen along with the fins 120, 120′ which allow air to pass up through the access point 1000 cooling both the front and rear surfaces of the main housing in which the central processing unit and various other heat generating components of the access point are located.

The FIG. 10 is an internal antenna version of a closed outdoor access point 1000 which has cooling fins between the front and main housing portions allows air to pass through the device and cool both the main and front assemblies. Watertight connectors allow for the supply of power and antenna connections 140. Cooling fins on the back of the main housing 102 which maybe be secured against a wall allow for air to pass between the wall and main access point housing even when secured directly to a wall. Thus air can flow around each side of the main and front housing in both wall and poll deployments since the arrangement of cooling fins allow for air flow between and behind the front housing 104 and main housing 102. Air can also pass along the front of the front body since it is normally exposed in either the open or closed positions access point modes of operation. A pressure vent 155 is included to allow venting in the case of pressure build up, e.g., due to heating, without letting water in.

FIG. 11 is a side cut away view 1200 of an exemplary access point which can be the same or similar to the access point 1000 shown in FIG. 1 or any of the other figures. In FIG. 11 the antenna elements of the BLE antenna array 204 are represented by discs included in the front housing 104. WiFi antennas are represented by rectangular blocks 281. Also visible is mounting board 1208, e.g., a printed circuit or other rigid board, to which the antenna elements 204, 281 are mounted. In the FIG. 11 example the front housing 104 also includes a position sensor 212. While WiFi antenna elements are present an external WiFi antenna can be connected to antenna terminals 1202 and used instead of the internal WiFi antenna elements 281. Board 1204 represents a rigid board to which the components 402 in the main housing including the CPU 208 can be and sometimes are secured.

FIG. 12 is a view 1300 of an exemplary access point, such as the access point 1000 of any of the other figures, with the front cover being shown as transparent allowing the BLE antenna array 204, WiFi antennas 281, tilt sensor 212 and other elements in the front housing to be seen. The Bluetooth antenna array 204 as shown in FIG. 12 can be used in the vertical or horizontal front assembly positions with knowledge of the position being known from the position sensor 212 allowing the orientation of the front housing 104 and thus the components included such as antennas 204, 281 to be taken into consideration when making WiFi coverage and/or Bluetooth coverage area predictions that can be used, e.g., to facilitate location determination.

While in various embodiments the main housing 102 is connected to the front housing 104 via a hinge 108, it should be appreciated however that the hinge 108 could be, and in some embodiments is, secured to the inner cover 106 which would still allow the front portion 104 to move relative to the components in the main body 102.

In some embodiments a screw, clip or other reusable fastener 107 is used to secure the front housing 104 in a closed position against the main body when the access point 100 is used in a closed position. The fastener 107 is located at the top center of the outside cover and secures the cover to the main body 102 or inners cover 106. The clip 107 can be snapped or unsnapped by pressing the outer housing 104 against the main body 102 or pulling on the other housing 104 to move the outer housing 104 to the open position. A receiver portion 107′ of the clip 107 maybe and sometimes is included on the main body 102 or inner cover 106 at a location where it will contact the clip 107.
